How many faces does an octagonal prism have? An octagonal prism has 10 faces. The octagonal prism can be seen to have ended shaped like octagons. That's an 8-sided figure. is a 3-dimensional form, and if it has octagons on each end, it is going to have 8 faces. That's a face for each side of the octagon. The 8 faces of the body of the prism are added to the two faces (one on each end) for a total of 10 faces. (The illustration is a pentagonal prism.). An n-gonal prism has n+2 faces.

How many faces, sides, and vertices does this dodecahedron have? Report Abuse. 10 faces, 38 sides and 25 vertices. In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα 'twelve' + εδρον 'base', 'seat' or 'face') is any polyhedron with twelve faces, but usually a regular dodecahedron is meant: a Platonic solid.

Lens Form: Sphere, Cylinder, and Axis A cylinder curve is curved along a single axis and flat along the perpendicular axis. Furthermore, while the focus of a spherical curve is a single point, the focus of a cylinder curve is a line. The meridian along which there is no cylinder power in the lens and consequently the meridian of the cylindrical focus is the cylinder axis. The cylinder axis is expressed in degrees between 0 and 180. Most prescriptions have some combination of spherical and cylinder curves. A lens that combines spherical and cylinder curves is called a compound lens or toric.

How many faces, edges and vertices does have a pentagonal prism have? Count them. Faces: 5+2=7. Edges: 5+5+5=15. Vertices: 5+5=10. More generally, a prism whose bases are n-gons have n+2 faces, 3n edges, and 2n vertices. Note that for all of them that Euler's formula holds: #faces–#edges+#vertices = 2.

- This formula is also valid for cylinders. Hence, if the radius of the base circle of the cylinder is r and its height is h, then: Volume of a cylinder = π r 2 h. Also in that module, we defined the surface area of a prism to be the sum of the areas of all its faces.For a rectangular prism, this is the sum of the areas of the six rectangular faces.ence, if the radius of the base circle of the cylinder is r and its height is h, then: Volume of a cylinder = π r 2 h. Also in that module, we defined the surface area of a prism to be the sum of the areas of all its faces.

Formula Volume of a Cylinder How to find the Volume of a Cylinder. This page examines the properties of a right circular cylinder. A cylinder has a radius (r) and a height (h) (see picture below). This shape is similar to a soda can. The surface area is the area of the top and bottom circles (which are the same), and the area of the rectangle (label that wraps around the can) Cylinder Volume Formula Practice Problems on Area of a Cylinder

How many flat surfaces has the cylinder? A cylinder has 2 flat surfaces and 1 curved surface. In differential geometry, a cylinder is defined more broadly as any ruled surface spanned by a one-parameter family of pa … rallel lines.s such it can have any number of flat surfaces but need not have any at all. A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinder respectively; these have no flat surfaces. 7 people found this useful.

"Faces on a sphere? One of my fifth grade students asked the question "" How many faces does a sphere have?""" The mapped image still has vertices's and edges and faces. They are the same amount of faces as the original polyhedron. Now imagine any polyhedron or shape inside the sphere. You can do the same with as many sided and faced shape as you want. Thinking this way you can view the sphere having infinite faces because you can map out any shape/polyhedron this way, no matter the number of faces.

- Mathematicians commonly write this as. V = B • h. Finding the volume of a cylinder is the exact same formula! In other words: Volume = (Area of base) • height. Volume = (Area of a circle) • height. Volume = (π • r • r) • h. Example 1. This cylinder has a radius of 4 cm and a height of 10 cm. Find its volume. V = B • h. V = (π • r • r) • h. V = (3.14 • 4 • 4) • 10. V = 502.4 cm^3. Example 2. This cylinder has a diameter of 6 cm and a height of 9 cm.

antibiotics Similarly, some antibiotics may have secondary uses, such as the use of demeclocycline (Declomycin, a tetracycline derivative) to treat the syndrome of inappropriate antidiuretic hormone (SIADH) secretion. Other antibiotics may be useful in treating protozoal infections.

- If a regular polyhedron has 12 vertices, and 30 edges, then how many faces does it have? Let we \(V\) be the number of vertices, \(E\) the number of edges, and \(F\) the number of faces. \[ \begin{align} V - E + F &= 2 \\ F & = 2 - V + E \\ & = 2 - 12 + 30 \\ &= 20. Thus, a regular polyhedron that has 12 vertices and 30 edges, has 20 faces.

- You can think of the volume of the cylinder as the volume of the area of the base being extended throughout the height of the cylinder. Since you know that the area of the base is 3.14 in.2 and that the height is 4 in., you can just multiply the two together to get the volume of the cylinder. 3.14 in.2 x 4 in.

Is it possible to double the volume of a cylinder by doubling it's height? If the radius and height of a cylinder are both doubled, then its surface area becomes 4 times what it was originally, and its volume becomes 8 times as much.

Cuboids, Rectangular Prisms and Cubes Cuboids, Rectangular Prisms and Cubes. Go to Surface Area or Volume. A cuboid is a box-shaped object. It has six flat faces and all angles are right angles. And all of its faces are rectangles. It is also a prism because it has the same cross-section along a length. In fact it is a rectangular prism.

Cuboid A rectangular cuboid. A cuboid is a 3D shape. Cuboids have six faces, which form a convex polyhedron. Simply speaking, cuboids are made from 6 rectangles, which are placed at right angles. A cuboid that uses square faces is a cube, if the faces are rectangles, other than cubes, it looks like a shoe box. Properties of a Cuboid are:

Shape: Face The prism has two bases, all one needs to know is how many other faces it has. That is determined by the number of sides on the base. A hexagonal prism will have the two hexagonal bases, and six more faces, one for each side of the hexagonal base, for a total of eight faces. Children are often quite pleased when they discover, on their own, that they can figure out the number of faces without counting.
